Does anybody have an opinion on MVVS 26 vs OS 160 performance. I have an OS 160 with 18x8 doing 8000 rpm are these figures realistic from a MVVS 26 straight out of the box
Cheers
I'll try the 26 in this baby this weekend tell you feedback, I have had to make some changes in the bisson pitts muffler cause it was restrictive, 18-8 menz must be arround 7,800 wich would be more than enougth to this plane.
I had the OS 160 in this plane, but after fliying it i decide to move to the mvvs 26 and avoid the glow, in fact this is one of the few planes were i would install an engine smaller than 50cc due to the extremly ligth weigth plane and the difference with the tank empty is only 9 oz between them
Engine is completly in the cowl except the sparck plug mounted @ 87º (not at 90º) just the same than OS 160.
